Kiss and Switch: The Cursed Vampire

Daphne's fiancé abandoned her at their wedding, driven by a desperate desire to save his old lover, Kitty, from the clutches of the vampire king. In an act of betrayal, he married Kitty instead and resorted to a forbidden blood exchange ritual. To settle the ancient debt of the Hanbo family, he deceived Teos, offering Daphne as a sacrifice. Daphne perished on the sacrificial altar, but to everyone's shock, she awakened in the embrace of a vampire, destined to be his eternal companion. When Paul, Daphne's former fiancé, learned of her death, the weight of his guilt and grief drove him to madness.
